Certificate of Appropriateness Process
The CA is the gate for essentially all exterior work in College Street Historic District. Appendix G §7(a): you may not "alter … any portion of the exterior … or place, construct, maintain, expand or remove any structure" without one. A CA can be required even for work that doesn't need a building permit — and it's required in addition to the building permit, never instead of it.
When you need one
- Any exterior alteration visible change: siding, windows, doors, roofing material change, porches, paint color change (on wood elements — see Minor Exterior Alterations (Staff-Level)), fences, additions, outbuildings, driveways/hardscape beyond thresholds, solar, mechanical placement…
- New construction, expansion, or removal/demolition of any structure (Demolition and Economic Hardship adds more steps)
- If in doubt: what doesn't need one is defined by Ordinary Maintenance Exemption (in-kind, no change in design/material/color/appearance)
The application (App. G §7(c) + city form)
File with Development Services / Historic Preservation staff:
- Applicant + property info, owner signature
- Detailed description of proposed work
- Current photos (historic photos help — commissioners respond well to them)
- Drawings to scale (8.5×11 or 11×17), material + color samples
- Residential extras (§7(d)(1)): photos showing the full width of adjacent properties both sides (corner lot: also the structure across the street) and street-facing elevation drawings including neighbors' elevations — the Commission literally judges your design against its neighbors, so these exhibits frame the whole argument.
Deadline: complete application 4 weeks before the meeting (meetings: 4th Wednesday, 6 pm, City Hall). Staff consultation first is expected — see Staff and Ex-Officio; in practice the Historic Preservation Officer shapes what reaches the agenda and how it's presented.
Review standards (what you're judged against)
- College Street Preservation Criteria (Ord 93-58) — district-specific, binding
- Secretary of the Interior Standards — mandatory lens for HL-overlay properties
- Grapevine Pattern Book (2025) — binding for residential (Township-wide), incl. hard caps: 35 ft max roof height, ≥1,200 sq ft living area, 3,400 sq ft max floor area (per §7(e)), 40% max lot coverage, no front-entry garages unless rear half of lot, lot width rules (§7(d)(2))
- Detached garage/carport ≤500 sq ft + storage building ≤200 sq ft don't count toward floor area (§7(d)(2)c)
- Minor adjustments possible via §7(e) (HPO + Development Services + CVB director recommendation) — but never to the 35 ft / 3,400 sq ft / 40% caps
The hearing
Public hearing with posted notice + mailed notice to adjacent owners ≥5 days ahead. Proponents and opponents speak. Commission must act within 60 days of a complete application: approve / approve with conditions / deny — always in writing, with reasons (§7(f),(g)).
Decision letter arrives by certified mail. A CA does not equal a building permit — and for Township residential work, a documented pre-construction meeting (owner + contractor + Historic Preservation Officer + Building Inspector) is required before the permit issues.
If denied
Appeals to City Council — 30 calendar days from receipt of the written decision. Council's decision is final and unappealable (§13).
Field notes (from the minutes corpus → keep updated)
- See Voting Patterns and Tendencies and Playbook - Getting to Yes for how this process runs in practice — conditions of approval are the Commission's favorite tool; expect material/spec conditions rather than outright denials when staff supports the application.
